On Script Interpolation / Curved Strokes

[Yoooi]

So when we add tons of extra actions to try to ‘override’ what the firmware does to smooth things out, it just gets confused and we get jerky, inaccurate motions. I think the best thing to do is to keep scripts simple and accurate, and let the firmware do its job. It also means that our scripts are more likely to work with more kinds of devices, including devices that haven’t been invented yet

Well I would hope that future devices will have better motors the launch, and better api than the handy.
I wouldnt make everything for the lowest common denominator device because we will be stuck with super simplified funscripts forever. Current scripts lack any acceleration and are just triangle waves.

Oh yeah totally - I more meant that like, adding too much detail might add information that works against the way the motor controllers and stuff are designed to work. So in your example with the banana-beatdown, I’d definitely script it in the simpler way.

Adding many points to achieve a smooth curve is currently just a solution to funscript limitation.
Thats why I suggested using tangents instead, because then you can send positions and tangents to the device and it can perform smooth moves, instead of having to send small linear steps. Kinda like spline moves (G5) in gcode.
Only problem is that all devices would have to support this kind of moves, but scripter software could save two versions of the script, one with tangents, and one where the splines are sampled to linear steps.
